When Dr. Nefarious marooned Ratchet and Clank on Morklon, they encountered Yurik who, despite the overwhelmingly depressing conditions of the planet, managed to cheerfully inform the duo on the historic battle of Gimlick Valley, indicating that he may have been a tour guide for the area. However, after his description of the battle, Yurik was overcome by regret and sadness about Zahn Gribnak being captured, imprisoned, pardoned, imprisoned again and killed.
When Ratchet and Clank used a time rift to arrive at the battle, Yurik ran to the duo to tell them that the Agorians kidnapped Zahn Gribnak, the Fongoid Chief. Ratchet, Clank, and the other Fongoids managed to free Zahn and his bodyguards from their prison.
Zahn saw Yurik and was disappointed he was not in the shelter with the others. Yurik then explained that Ratchet and Clank were there to help them before taking shelter in a cave.
When Ratchet and Clank returned to the present, other Fongoid children recalled being told the story of the battle and how Yurik called Clank a "talking lunchbox." This might have meant that Yurik was one of the survivors, ten years later.
